Note that in such setups (64 bit kernels and 32 bit userspace) *some* software will not work correctly (perhaps it's limited to tightly kernel-userspace integrated software). One example is open-iscsi - you won't run 32 bit open-iscsi userspace on a 64 bit kernel (at least it was impossible a couple of months ago). -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
